MEANS FOR PURIFYING AND REGULATIN'G WATER.

Specification of Letters Patent.

Patented March 31, 1908.

Application filed July 27, 1907. Serial No. 385,872.

To all whom it may concern:

Be it known that I, IIORAOE E. SIBsoN, a citizen of the United-States,and resident of and whose post-ofiice address is 67 19 Germantown road,Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful improve ments in Means forPurifying and Regulating Water, of which the following is aspecification.

My invention relates to improvements in apparatus for heating, purifyingand regulating a supply of liquid, and more particularly to-means forinsuring an adequate supply of said liquid therefrom.

My improvements are specifically adapted for use in connection withwater heaters and purifiers of the type illustrated in the accompanyingdrawings and described in the following specification. I do not,however, limit myself to this specific use or application of myinvention, but, on the contrary, the same is applicable to and adaptedfor any use where the purification and regulation of liquid is required.

In heaters and purifiers of the particular described type, which areWell-known in the art, filters are employed for the purpose ofseparating impurities from the water passing therethrough, so as torender the same completely purified for use. These filters eventuallybecome choked or clogged with the impurities that have been thus caughtor retained by the substance of the filter. This choking or clogging isaugmented when a chemical reagent is used to cause a precipitation ofthe suspended impurities. I This clogging of the filtering elementresults in an inadequate and insufficient supply of water for purposesfor which it is required and it, therefore, becomes necessary tosupplement the amount of water that passes through the filter with anincrement of chemically treated but unfiltered water. By-passes orpassage ways around the filter have been used for the purposeoffurnishing this increment, and it is an improvement in such by-passesor passageways that forms the subjectmatter of my present invention.

Some of the ob ects of my improvement,

among others, are to provide an exterior circuitous by-passorpassageway, of such construction and location that, when the filteringelement becomes partially or wholly inoperative, the increment will betaken from a point most remote from the cold water inlet, thus insuringthe bypassing from that strata of water that has had the longesttreatment within the heater; to provide an addition to the heater, or,in other words, an auxiliary compartment wherein the unfiltered waterby-passed therethrough will be given further time for the precipitationof the contained impurities therefrom; and other objects that willhereafter more fully appear.

In the accompanying drawings I have illustrated an embodiment of myinvention, Where Figure 1 represents an elevation of a feed water heaterand purifier to which my invention has been applied. Fig. 2 a top viewthereof. Fig. 3- an end view thereof. Fig.

4- a sectional elevation of my improved bypass taken on line -A--A ofFig. 3. Fig. 5* a sectional end elevation thereof.

Throughout the several figures of the drawings like numerals indicatelike parts.

Referring to Figs. 1 and 2, 1 indicates a heater; 2- the exhaust inletfrom engine or other source of steam supply; 3 a separator; 4 theexhaust pipe from theheater to the atmosphere; 5- a cold water supplypipe; 6 the inlet for the chemical solution or reagent, generally usedfor the purpose of formin with the impurities in the water, an insolub eprecipitate; '7 a valve in the cold water supply pipe 5- automaticallyoperated through an intermediate mechanism by float 8 located in floatchamber 9, and governed by the water level in the sys tom; 9' a vent forsaid float chamber; 10 a water seal; 11- waste pipe; 12 the filter-bed12- a dividing partition; 13- the exterior circuitous by-pass; 14- theoutlet to the feed pumps.

Referring now to Figs. 3, 4 and 5, the bypass 13-, (which may be eitherformed ter-bed 12- and opening into compartment or passageway 17-, whileaperture -1 9 is situated below the filter-bed 12- near the bottom ofthe heater, and is provided with a hood 20-, and opens into compartmentor passageway 16.

2l indicates a drain tor compartment 17-, and 21 a vent for the by-pass13.

14 indicates the outlet from the compartment 17 to feed pumps (notshown).

It will be readily understood that the bypass operates automatically andis governed solely by the condition of the filter ].2.

The normal working line is indicated at 22, 23-, supplementary line at24, indicating successive steps in the operation of the heater and theby-pass.

The mod'us op'ercmdi is as follows: The cold water enters through pipe 5in such quantities as governed by float L- in the float chamber 9,operating the regulating valve 7'. It wi I be understood that the float-8 can be adjusted to operate the 25 valve 7 at any predetermined waterline. The chemical reagent enters through pipe 6 and mixes with the feedwater; the exhaust steam enters through inlet 2 through the separatingchamber -3 into the heater, all of which is well-known and consequentlyneeds no further explanation. Upon the mixing of these supplied elementsa precipitation immediately begins of the contained impurities. Thewater normally passes down through the heater around partition 12, upthrough the filter-bed 12-, through aperture 18, into passage 17 of theexterior by-pass 13, as indicated by arrows ab (Fig. 4) to the feedpumps.

begins to clog or choke, by reason of the precipitates lodging therein,the water line within the exterior by-pass rises from normal, asindicated at -22-, to line of overflow, as

indicated at 23, thus overflowing partition -15, as indicated by arrowsc (Figs. 3 and 4), into compartment or channel 17 of by-pass 13, Whereit meets and commingles with the filtered supply coming through aperture18. Should the water line within the heater and by-pass becomeabnormally high as indicated by the supplementary line -2l, the supplythrough feed inlet 5 will be cut off by the rise of float 8 whichoperates the valve 7; but as soon as the water line falls below the toppartition 15-, by reason of the same being drawn oil by the feed umps,the valve 7 will open upon the fal of the float 8 in 0 float chamber 9and permit a further supply of water through feed pipe 5. Thus it willbe seen that a sufficient increment is diverted around the filter tomake up the deficiency caused by its choking or clog- 5 ging, andsufficient and adequate supply fur- Now, as soon as the filter nished tothe feed pumps. It is further seen that by the use of a by-pass of myimproved construction, the increment is taken from that point in theheater most remote from the feed water inlet, thus insuring theby-passing of the water that has been longest subjected to treatment,and which contains the least amount of impurities, since it has had thelongest time for precipitation and agglomeration of the impurities; and,further, the water being thus by-passed up through an exteriorcircuitous channel or compartment, as indicated by the arrows (Ze--f(Fig; 4) is afforded further time for precipitation, thus greatlyincreasing the efiiciency of the apparatus in rendering the increment tothe filtered supply in as nearly as possible a completely purifiedcondition. The precipitated matter deposited in channel or compartment17 due to this further treatment is removed through the drain 21,provided for the purpose. It is also apparent that my improved by-passbeing constructed exterior of the heater or tank and separabletherefrom,

is capable of attachment to existing purifiers, where more efficientpurification is wanted.

I do not limit myself to an exterior circuitous by-pass of theparticular formation shown, but, on the contrary, the same may beconstructed in divers ways and still come within the scope and tenure ofmy claims.

What I claim and desire to protect by Letters Patent is:

1. In a heater, a filter and an exteriorly arranged vertically reversedby-pass.

2. In a feed water heater, the combination of an interior horizontalfilter and an exteriorly arranged vertically reversed by-pass.

4. In a heater, the combination of a feed supply; an exhaust steamsupply; a chemical supply; afilter; anexteriorverticallyreversed by-passadjacent the filter for automatically supplementing the outflow from thefilter by an increment of chemically treated but unfiltered water.

5. The combination of a heater; a filter; a 5 by-pass exterior and aboutthe filter; said bypass formed of two channels; openings into saidby-pass above and below the filter; an outlet and a drain for saidby-pass in one of said channels.

6. A filter, an exteriorly arranged vertically reversed by-pass;openings above and below said filter communicating with said by-pass.

7. A filter; a supplementary chamber exterior thereto; a partitionwithin said cham ber dividing it into two compartments; an openingconnecting the two compartments above said partition; an opening fromabove the filter into one compartment, and a hooded opening below thefilter into the other of said compartments, and a drain from saidfirst-named compartment.
